Abstract
Disclosed are a resin composition comprising a polylactic acid resin and a polyacetal resin, and such a resin composition in which the polylactic acid resin and the polyacetal resin are kept miscible with each other. The resin composition has good moldability, workability, mechanical properties, heat resistance and transparency, and may be worked into moldings, films and fibers for practical use.
